Highly Efficient Bi4Ti3O12/g-C3N4/BiOBr Dual Z-Scheme Heterojunction Photocatalysts with Enhanced Visible Light-Responsive Activity for the Degradation of Antibiotics

“…The impurity diffraction peaks do not appear here, indicating that Bi 4 Ti 3 O 12 was successfully prepared. , The BOB shows the (001), (002), (101), (102), (003), (004), and (104) crystal planes at 10.97, 21.79, 25.30, 31.64, 33.26, 44.64, and 50.53° that exhibit characteristic diffraction peaks, respectively, which is consistent with the tetragonal crystal system of BOB (JCPDS#09-0393) . The characteristic diffraction peak of CN can be designated as the (002) crystal plane at 27.42°. , Compared with pure Bi 4 Ti 3 O 12 and CN, the 10 BTO/CN composite catalyst includes orthorhombic Bi 4 Ti 3 O 12 diffraction peaks and CN characteristic diffraction peaks at the corresponding positions, and the diffraction peak intensity of CN lessened, which may be caused by the decrease of the CN content. It is noteworthy that the diffraction peak angle connected to the (282) crystal face of Bi 4 Ti 3 O 12 is shifted slightly (Figure b), indicating that Bi 4 Ti 3 O 12 interacts with CN to create a heterojunction, which is not a simple physical composite. , Furthermore, BOB and 10 BTO/CN were compounded to obtain 50 BTO/CN/BOB composite photocatalyst.…”

Porous Nitrogen-Defected Carbon Nitride Derived from A Precursor Pretreatment Strategy for Efficient Photocatalytic Degradation and Hydrogen Evolution

“…On the other hand, N defects can reduce the bandgap and serve as electron traps to promote charge transfer and separation efficiency. Moreover, the stability of a photocatalyst is an important factor to evaluate its application potential. − Figure S5 shows that the photocatalytic degradation of PDCN remains relatively stable after four consecutive cycles, confirming that PDCN has a high degree of photocatalytic stability.…”

A potential link between the structure of iron catalysts and Fenton-like performance: from fundamental understanding to engineering design

“…5(E and F)). 109 Besides, N 2 adsorption–desorption isotherms, which are generally employed to investigate the pore characteristics and specific surface areas of a material, 140 can also confirm the spatial nanoconfinement of nanoparticles. In general, confining nanoparticles in the internal pores of porous materials probably leads to the decrease of the Brunner–Emmet–Teller (BET) surface area and pore volume owing to the part blockage of the pore system.…”
